Abstract
A rotary electric machine includes a rotor including a plurality of magnet sections arranged along a rotational direction of the rotor so that polarities of the magnet sections change alternately, and a stator including armature coils, and being disposed to confront the rotor across an air gap. Permanent magnet flux which is not linked with one of the air gap and the armature coils is higher than permanent magnet flux which is linked with the air gap and the armature coils in a no-load state.
